The evaporative condenser condenses a refrigerant gas from agaseous to a liquid state. As the refrigerant gas flows through a coil from top to bottom sprayed with water and countercurrent air, it condenses and changes phase. Medium to large refrigeration systems are usually water-cooled, especially if they use ammonia as a refrigerant.

The choice of a water-cooled condensing unit such as W-tech evaporative condensers over air-cooled units is simple: - Consistent performance throughout the year due to lower condensing temperatures - Higher thermal efficiency during winter/summer months - Optimal efficiency due to use of recirculating water in fall with countercurrent air - Lower power consumption compare ...
